Isnt that very vague and very subjective? It just seems to me that if the situation arises and they just dont want somebody to have a gun, they absolutely have a way to do it without any due process. You can be judged incompetent and they can just take your guns away without any recourse.

And what happened with confidentiality between a doctor and patient? Wheres the criteria? Where is the line? Who decides the difference between someone who dealing with depression and anxiety and someone who wants to do harm with a gun? Where is that line? Who makes that judgement?

Confidentiality ends when someone indicates that they may be a threat to themselves or others whether a gun is involved or not. In fact if such behavior is observed it is the duty of the healthcare provider, whether a doctor or therapist to notify the authorities. This isn't new...at all. The questions about who decides it, makes the judgment, etc, are not just surfacing because of this and they have never been an issue in the past. Same goes for suspected child abuse. These laws are in place for the safety of the patient and society in general.
